Bitrate is the most important parameter of any lossy codec. Bit rate is usually measured as the number of "bits per second" (bps) at which data in an audio stream is transmitted. A higher bit rate means that an MP3 contains more information. An MP3 file at 128 kbps transmits 128,000 bits per second when played back. The higher the bitrate, the more information is played back and the higher the sound quality. There is really no recommended value, it just depends on your needs, but most people will not notice a difference in quality after reaching 256 kbps.
How I can change bitrate of MP3 file?
Do you want to reduce the size of a large mp3 file or just combine several MP3 files with different bitrates into one? This is easy enough. But please never increase the bitrate of an existing MP3 file to get higher quality! It is impossible, because some audio data is already lost during the original encoding, and you will lose even more after recoding. All you will get is an increased file size.
Audio Converter Plus can change the bitrate of any audio format, so you can easily reduce the size of MP3 for sending to your mobile device or as an email attachment.
